Peptide transporter 2 (PEPT2) expression in brain protects against 5-aminolevulinic acid neurotoxicity.
The proton-coupled oligopeptide transporter PEPT2 (or SLC15A2) is the major protein involved in the reclamation of peptide-bound amino acids and peptide-like drugs in kidney. PEPT2 is also important in effluxing peptides and peptidomimetics from CSF at the choroid plexus, thereby limiting their exposure in brain. In this study, we report a neuroprotective role for PEPT2 in modulating the toxici...
متن کاملSynergistic Cytotoxic Effect of Gold Nanoparticles and 5-Aminolevulinic Acid-Mediated Photodynamic Therapy against Skin Cancer Cells
Background: Photodynamic therapy (PDT) is a promising therapeutic modality for the treatment of cancer and other diseases. In this study, the epidermoid carcinoma cell line A431 and the normal fibroblasts were used to investigate whether gold nanoparticles (GNPs) can induce an increase in cell death during PDT using 5-aminolevulinic acid (5-ALA) as a photosensitizer.Methods: Human fibroblast an...
متن کاملEffects of 5-aminolevulinic acid-mediated sonodynamic therapy on macrophages
BACKGROUND Inflammatory cells exhibit an elevated level of protoporphyrin IX (PpIX) after the administration of 5-aminolevulinic acid (ALA). Here, we investigate the sonodynamic effects of ALA-derived PpIX (ALA-PpIX) on macrophages, which are the pivotal inflammatory cells in atherosclerosis. METHODS AND RESULTS Cultured THP-1 macrophages were incubated with ALA. Fluorescence microscope and f...
متن کامل5-Aminolevulinic acid synthesis in Escherichia coli.
A hemA mutant of Escherichia coli containing a multicopy plasmid which complemented the mutation excreted 5-aminolevulinic acid (ALA) into the medium. [1-14C]glutamate was substantially incorporated into ALA by this strain, whereas [2-14C]glycine was not. Periodate degradation of labeled ALA showed that C-5 of ALA was derived from C-1 of glutamate. The synthesis of ALA by two sonicate fractions...
متن کاملTransport of 5-aminolevulinic acid by the dipeptide permease in Salmonella typhimurium.
In a previous search for mutants of Salmonella typhimurium that are defective in heme synthesis, one class that is apparently defective in 5-aminolevulinic acid (ALA) uptake (alu) was found. Here, I describe the characterization of these mutations. The mutations all map to a single locus near 77.5 min on the genetic map, which is transcribed counterclockwise. Nutritional tests, genetic and phys...
